The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Shown in Fig. 1～3, a kind of condenser for outdoor unit of air conditioner 1 comprises dual-row condenser U pipe 1-1, the inlet pipe of described condenser is arranged on lee face 5, go out pipe and be arranged on windward side 4, as shown in Figure 4, described condenser 1 is provided with total inlet pipe 2, the top seal of total inlet pipe 2, lower ending opening, cold-producing medium enters from the lower end, and described total inlet pipe 2 is divided into two groups of inlet pipes, accordingly, condenser windward side 4 is provided with two groups and goes out pipe.The adjacent setting of each group inlet pipe, each organizes out the also adjacent setting of pipe.First group of inlet pipe is respectively inlet pipe 2-1 and inlet pipe 2-2, and second group of inlet pipe is respectively inlet pipe 2-3 and inlet pipe 2-4, and first group goes out pipe and be respectively out pipe 3-1 and go out to manage 3-2, and second group of inlet pipe is respectively out pipe 3-3 and goes out to manage 3-4;
As shown in Figure 4, the schematic flow sheet of condenser: each group adjacent setting of inlet pipe also is divided into upper and lower two branch roads, upper and lower two branch roads that each group inlet pipe is divided into are relative " U " shape structure of opening, being inlet pipe 2-1 is down " U " shape to going out to manage the I branch road 6-1 that 3-1 forms, inlet pipe 2-2 just is being " U " shape to the II branch road 6-2 that goes out to manage 3-2 formation, and I branch road 6-1 and II branch road 6-2 constitute the top set road 6 of whole condenser;
Similarly, inlet pipe 2-3 is down " U " shape to the I branch road 7-1 that goes out to manage 3-3 formation, and inlet pipe 2-4 just is being " U " shape to the II branch road 7-2 that goes out to manage 3-4 formation, and I branch road 7-1 and II branch road 7-2 constitute the inferior division road 7 of whole condenser;
The top set road 6 on condenser top is connected to condenser super cooled sect co-domain 3-5 by three-way pipe 8, jumper pipe 9, the inferior division road 7 of condenser is connected to territory 3-6 under the condenser super cooled sect by three-way pipe 8, jumper pipe 9, and the outlet of territory 3-6 is connected by a minute outlet, separatory capillary 3-7 and always goes out pipe 3 under cold then section co-domain 3-5 and the super cooled sect.Described jumper pipe 9 is for connecting the straight tube of described three-way pipe 8 and condenser lower end super cooled sect.
As shown in Figure 6, three-way pipe 8 comprises general import pipe 8-1, arm a8-2, arm b8-3, and described arm a8-2 is two branches that same root canal curvature becomes U type pipe with arm b8-3, and described general import pipe 8-1 is arranged on the described U type pipe.Described general import pipe 8-1 is vertical with the plane of described U type pipe, and described arm a8-2 is identical with the internal diameter of arm b8-3.
During air-conditioner work, the vapour-liquid two phase refrigerant vertically flows to three-way pipe 8 from general import pipe 8-1, because the two ends caliber is in full accord, and agravic factor is separated influence, therefore the two phase refrigerant flow that enters two ends is consistent with mass dryness fraction, it is almost completely identical with mass dryness fraction promptly to enter upper and lower two branch road coil pipe refrigerant flows, thereby has effectively improved system's heating capacity and Energy Efficiency Ratio.
As shown in Figure 7, outdoor condenser wind field wind speed is " V " font and distributes, and promptly wind speed is big up and down, and is middle little.During kind of refrigeration cycle, import is an overheated gas, exports to the subcooled liquid of certain degree of supercooling is arranged, and the density between gas and the liquid refrigerant differs greatly, therefore the flow of cold-producing medium from top to bottom each branch road successively decrease, promptly go up a branch road coil pipe flow greater than next branch road coil pipe flow.Heat circulation time, import is the very little two-phase fluid of mass dryness fraction, exports to be overheated gas, and the flow of cold-producing medium each branch road from the bottom up successively decreases, and promptly next branch road coil pipe flow is greater than a last branch road coil pipe flow.
Therefore freeze, heat flow process and wind field wind conditions for equilibrium, adopt above-mentioned U pipe layout designs.Heat circulation time, the condenser inlet cold-producing medium is two-phase flow, and is even for top set road 6, inferior division road 7 separatory, increases by 1 separatory with capillary (totally 2) in each import department.Cold-producing medium is in condenser part (super cooled sect during kind of refrigeration cycle) vaporization evaporation, therefore the mass dryness fraction that arrives the two phase refrigerant of each branch road further becomes big, therefore use above-mentioned three-way pipe to carry out separatory, make the refrigerant flow and the mass dryness fraction uniformity that enter I branch road and II branch road higher, two branch roads on same inferior division road 7 also are so, thereby further improve the uniformity that heats separatory.
Present embodiment is as different from Example 1: as shown in Figure 5, top set road 6 is connected to territory 3-6 under the condenser super cooled sect by three-way pipe 8, jumper pipe 9, inferior division road 7 is connected to condenser super cooled sect co-domain 3-5 by three-way pipe 8, jumper pipe 9, and the outlet of territory 3-6 is connected by a minute outlet, separatory capillary 3-7 and always goes out pipe 3 under cold then section co-domain 3-5 and the super cooled sect.Other repeat no more with embodiment 1.
The above only is preferred embodiment of the present invention, is not to be the restriction of the present invention being made other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
